A building system that utilizes an improved beam and coupling system for building a frame or structure having improved strength and durability and improving performance and/or spanning distance of the beam.

Described herein is a System of Tubular Connections (STC) for a building method for constructing and fastening together any elongated symmetrical frameworks such as awning or fences, eliminating the need for other fastening methods such as welding. The STC consists of four (4) basic physical elements. Element 1 is any elongated symmetrical shape, for example tubing or 24 wooden boards. Element 2 is any threaded product. Element 3 is a tubing fastener used when Element 1 is symmetrical hollow tubing. Element 4 is the building block that the elongated symmetrical shape is screwed into or through.

A building system that utilizes an improved beam and coupling system for building a frame or structure having improved strength and durability and improving performance and/or spanning distance of the beam. The beams may include an installation aperture for receiving an internal coupler and an auxiliary aperture, which may be utilized to run cables or wires. The beams each include an inner wall that divides an interior of the beam into the installation aperture and the auxiliary aperture.
